Phosphatidylinositol is a she wolf with a mid-brown colored body, silver streaks and a yellowish under belly. She has dark skin and yellow eyes.
Phosphatidylinositol was named after a lipid which contains a phosphate group, two fatty acid chains, and one inositol sugar molecule. She joined the pack as an adolescent and proudly wears her full chemical name as her true name, and insists everyone else refers to her as such. Many other wolves in the pack who choose to shorten theirs out of convenience, but certainly not Phosphatidylinositol.
